14/41:7 = 2/41. To divide a fraction by a whole number, you multiply the numerator of the fraction by the inverse of the whole number. In this case, 7 is the same as 7/1, so the inverse would be 1/7.
Multiply the numerator of the fraction (14) by the inverse of the whole number (1/7): (14 * 1) / (41 * 7) = 14/287.
Therefore, 14/41 divided by 7 is equal to 2/41 or approximately 0.048.
Now let's move on to the second expression:
100:20/23 = 100 * 23/20. To divide a whole number by a fraction, you multiply the whole number by the reciprocal (flipping the numerator and denominator) of the fraction. The reciprocal of 20/23 is 23/20.
Multiply the whole number (100) by the reciprocal of the fraction (23/20): (100 * 23) / (20 * 1) = 2300/20.
Simplify the fraction by dividing the numerator and denominator by their greatest common divisor (GCD), which is 20: (2300/20) ÷ (20/20) = 115/1.
Therefore, 100 divided by 20/23 is equal to 115.
Let's move on to the third expression:
12/13:24/39 = 12/13 * 39/24. To divide one fraction by another, you multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 24/39 is 39/24.
Multiply the first fraction (12/13) by the reciprocal of the second fraction (39/24): (12 * 39) / (13 * 24) = 468/312.
Simplify the fraction by dividing the numerator and denominator by their GCD, which is 156: (468/312) ÷ (156/156) = 3/2.
Therefore, 12/13 divided by 24/39 is equal to 3/2 or 1.5.
Finally, let's evaluate the last expression:
1:61/3.
To divide a whole number by a fraction, you multiply the whole number by the reciprocal of the fraction. The reciprocal of 61/3 is 3/61.
Multiply the whole number (1) by the reciprocal of the fraction (3/61): (1 * 3) / (61 * 1) = 3/61.
Therefore, 1 divided by 61/3 is equal to 3/61 or approximately 0.049.
